You need some resourcefulness to locate these places, mind you :)
And good timing to use the stealth and potting
As for the skills, well, you need to execute the combo well and pick the right class to gank
So in other words, you hide in stealth and pickk on AFK people with low health, then run away? This is known as griefing in any other game, only MMO's reward this kind of behaviour. And sorry to be blunt but I have played a lot of MMO's and MMO's do not require nearly as much skills as other genres such as FPS or RTS, its mostly time spent getting your gear and using a lot of potions and items.
What I saw in that video is an Assassin griefing a bunch of people then running away, no skill really involved because the other people weren't really given much chance to react cause most were afk or minding their business. But Assassins can keep deluding themselves that their minimum effort, maximum reward Class is highly skill dependent.
